The object of this invention is to provide an improved constructional arrangement of ring spinning, doubling or twisting machine.

A machine in accordance with the invention comprises a plurality of unitary sections, each of which constitutes a complete frame having its building motion, spindles and drafting rollers (where provided), means for connecting the ends of each section to the adjoining sections in true alignment, and a headstock sectional unit comprising all the gearing for driving the building motion (and the drafting rollers) and the mechanism associated therewith.

A further feature of the invention is the provision in such a unitary sectional spinning or like machine, of a power-transmitting element extending throughout the length of the combined sectional units of the entire machine and into the headstock section Where it receives drivin motion, said. element having connections in each frame section whereby it transmits such driving motion to mechanism effecting the necessary reciprocatory movement of the spindle rails or ring rails, whichever of these members are employed by their rising and falling motion to perform the function of building the package of yarn or thread upon the spindles during the winding operation.

The manner in which the invention may be carried into effect is hereinafter described with reference to the accompanying diagrammatic drawings, in which Fig. 1 is a plan of part of a ring spinning machine comprising a number of sectional frames, each of which is a self-contained unit, but all having a common driving mechanism and transmission for the operation of the building motion; Fig. 2 is a section taken on the line IIII of Fig. l, and Fig. 3 is a perspective View of the spring-pieces or end-frames of two adjacent sectional units, spaced apart to show the means by which they are connected together when assembled in the construction of the machine.

Figs. 4 and-5 illustrate respectively a longitudinal elevation and a plan of parts of a modified embodiment of the invention.

It will be seen that in both cases the invention is illustrated in its application to machines in which the ring rails are stationary and in which the spindle rails are raised and lowered in reciprocatory movement to produce the desired formation of the yarn packages upon the spindles. It will however be understood that the invention is equally applicable to machines in which the situation is reversed, the spindle rails being stationary and the ring rails reciprocated.

Reference to the drawings shows that each unitary section of the machine comprises a pair of oppositely disposed spring-pieces or end-frames i and 2, respectively. These areconnected by the roller-beams 3 at the top and two angle-section longitudinal-1s 4, i at the base. Also connecting and suitably supported by the spring-pieces .l, 2 are the stationary ring rails 5, 5 and the intermediate rails 6, e, which latter are cross-connected by transverse members i the purpose of which-is hereinafter referred to. (The members i are shown only in Fig. 2, being omitted from Fig. 1 for the sake of greater clarity.) y

The spindle rails B, 8 made in lengths substantially equal to or very slightly less than the length of the frame-sections, are connected together across the machine by beams 9 furnished on their outer faces With blocks iii which are each arranged to slide in and be guided by a vertical groove il formed in a rib i2 cast in or attached to the inner face of the adjacent spring-piece. The headstock is indicated by the reference numeral i3. 7

The longitudinal power-transmitting element provided by the invention for effecting the rising and falling movement of the spindle rails consists in this embodiment of a shaft composed of a plurality of sections i l, hi each corresponding in length to the length of a frame section. At the headstock end of the frame section adjacent thereto the shaft-section i4 is coupled at IE to a rocking shaft [6 forming part of the headstock mechanism, and at the abutting ends of the sev eral frame-sections the various shaft-sections M are likewise coupled together by short piecing-up sections il so that the whole constitute collectively a single rocking shaft extending throughout the entire machine. In each frame-section a second short rocking shaft i8 is disposed parallel to the main rocking shaft i l and connected thereto by suitable gearing e. g. the-gear-wheels I9, 20, so that they rotate in opposite directions. Endless chains 2i depending from sprockets 22 on said rocking shafts l4 and i8 are attached to the two spindle rails 8 and serve to transmit raising and lowering motion thereto when the main rocking shaft It is operated at the headstock, said chains passing beneath tensioning sprockets 23 carried on pins 24 which are mounted in the aforementioned beams l. The shaft-sections M and M are supported by bearing brackets 25, 25 carried by the ring rails 5.

The spring-pieces I, 2 are maintained in true alignment in the course of assembly of adjacent frames by means of machined dowel-pins 25 adapted to register with carefully located holes 2! in the opposing faces of the spring-pieces. The spring-pieces are also apertured at 28 to receive the intermediate coupling-sections I! for the continuous rocking shaft 14.

In the modified embodiment which is illustrated in Figs. 4 and 5 of the drawings, the spring-pieces l, 2 are connected at the top by two parallel beams 29. In this case the longitudinal power-transmitting element consists of an endless driving chain 30 extending throughout the length of the entire machine from an oscillating sprocket (not shown) which forms part of the headstock mechanism. In each frame-section the spindle rails 8 are suspended by chains 3| from sprockets 32 on a pair of rocking shafts 33, 34 which are disposed transversely of the machine and spaced apart one near to each end of the frame-section, being mounted in bearing brackets suspended from said beams 29.

The endless driving chain 30 is arranged to engage a sprocket 35 on each of said transverse rocking shafts 33, 34 so as to transmit to the latter the intermittent reciprocatory motion impartedto the driving chain 30 by the oscillation of the said headstock sprocket. The sprocket 35 onthe furthermost transverse shaft of the last frame-section serves as the return sprocket for the driving chain 30. The weight of the spindle rails and the parts supported thereby is partially compensated by balance weights 36 which are suspended by straps 31 passed over pulleys 3.8. on the shafts 33, 34.

The constructional. arrangement is preferably suchthat when erected the sections of the spindle rails 8 are so relatively disposed that the distance separating the endmost spindles of each sectional unit is equal (or approximately equal) to the spindle-gauge in other parts of the machine. Thus, as can be seen from Fig. 1, the line of spindles in an erected composite machine presents the customary uniform appearance of a conventional machine, and retains the advantage possessed by the latter that the operative is easily able, by glancing along the machine, to detect any irregularity which may have occurred due to faulty performance of an individual spindle or a part connected therewith.
